ZTM.

A good zero turn cuts your time in half. A smaller good zero turn is better than a bigger cheaper made one. For example if you see a 24hp motor on a 60” stamped steel deck and the same motor on a smaller unit with a fabbed deck they will often be the same price. If you’re going to keep it for more than a couple of years your better off buying the better unit even if it’s smaller. On top of that the larger deck will have a slower mowing speed given the same motor. A good solid unit will give you 100s of hours of service with belt changes and the occasional pulley change assuming you service the motor. Reading up on them they are all rated in mph and acres/hour mowing.

^^This right here.

Been running the same Deere ZTR for 14 years. Kawasaki engine that has given not one ounce of trouble.

I've had good luck with John Deere zero turns.

The general consensus of guys who mow for as living is they would rather buy a used commercial thats in good shape than a new residential. I guess there is that much a difference.
